#FactCheck- Delhi Metro Rail Corporation Price Hike

Introduction:

Welcome to the second edition of our blog on Digital forensics series. In our previous blog we discussed what digital forensics is,  the process followed by the tools, and the subsequent challenges faced in the field. Further, we looked at how the future of Digital Forensics will hold in the current scenario.  Today, we will explore differences between 3 particular similar sounding terms that vary significantly in functionality when implemented: Copying, Cloning and Imaging.

In Digital Forensics, the preservation and analysis of electronic evidence are important for investigations and legal proceedings. Replication of the data and devices is one of the fundamental tasks in this domain, without compromising the integrity of the original evidence. 

Three primary techniques -- copying, cloning, and imaging -- are used for this purpose. Each technique has its own strengths and is applied according to the needs of the investigation.

In this blog, we will examine the differences between copying, cloning and imaging. We will talk about the importance of each technique, their applications and why imaging  is considered the best for forensic investigations.

Copying

Copying means duplicating data or files from one location to another. When one does copying, it implies that one is using standard copy commands. However, when dealing with evidence, it might be hard to use copy only. It is because the standard copy can alter the metadata and change the hidden or deleted data .

 The characteristics of copying include: 

• Speed: copying is simpler and faster,compared to cloning or imaging.
•  Risk: The risk involved in copying is that the metadata might be altered and all the data might be captured.

Cloning

It is the process where the transfer of the entire contents of a hard drive or a storage device is done  on another storage device. This process is known as cloning . This way, the cloning process captures both the active data and the unallocated space and hidden partitions, thus containing the whole structure of the original device. Cloning is generally used at the sector level of the device. Clones can be used as the working copy of a device .

Characteristics of cloning: 

•  bit-for-bit replication: cloning keeps the exact content and the whole structure of the original device. 
• Use cases: cloning is used when it is needed to keep the original device intact for further examination or a legal affair. 
•  Time consuming: Cloning is usually longer in comparison to simple copying since it involves the whole detailed replication. Though it depends on various factors like the size of the storage device, the speed of the devices involved, and the method of cloning.

Imaging:

It is the process of creating a forensic image of a storage device. A forensic image is a replica copy of every bit of data that was on the source device, this including the allocated, unallocated, and the available slack space .

 The image is then used for analysis and investigation, and the original evidence is left untouched. Images can’t be used as the working copies of a device.  Unlike cloning, which produces working copies, forensic images are typically used for analysis and investigation purposes and are not intended for regular use as working copies.

Characteristics of Imaging:

•  Integrity: Imaging ensures the integrity and authenticity of the evidence produced
•  Flexibility: Forensic image replicas can be mounted as a virtual drive to create image-specific mode for analysis of data without affecting the original evidence . 
• Metadata: Imaging captures metadata associated with the data, thus promoting forensic analysis.

Key Differences

• Purpose: Copying is for everyday use but not good for forensic investigations requiring data integrity. Cloning and imaging are made for forensic preservation.
• Depth of Replication: Cloning and imaging captures the entire storage device including hidden, unallocated, and deleted data  whereas copying may miss crucial forensic data.
• Data Integrity: Imaging and cloning keep the integrity of the original evidence thus making them suitable for legal and forensic use. Which is a critical aspect of forensic investigations.
• Forensic Soundness: Imaging is considered the best in digital forensics due to its comprehensive and non-invasive nature.
• Cloning is generally from one hard disk to another, where as imaging creates a compressed file that contains a snapshot of the entire hard drive or a specific partitions

Conclusion

Therefore, copying, cloning, and imaging all deal with duplication of data or storage devices with significant variations, especially in digital forensic. However, for forensic investigations, imaging is the most selected approach due to the correct preservation of the evidence state for any analysis or legal use . Therefore, it is essential for forensic investigators to understand these rigorous differences to avail of real and uncontaminated digital evidence for their investigation and legal argument.

Introduction

The hospitality industry is noted to be one of the industries most influenced by technology. Hotels, restaurants, and travel services are increasingly reliant on digital technologies to automate core operations and customer interactions. The shift to electronic modes of conducting business has made the industry a popular target for cyber threats. In light of increasing cyber threats, safeguarding personal and sensitive personal data on the part of the hospitality industry becomes significant not only from a customer standpoint but also from an organisational and legal perspective.

Role of cybersecurity in the hospitality industry

A hospitality industry-based entity (“HI entity”) deploys several technologies not only to automate operations but to also deliver excellent customer experiences. Technologies such as IoTs that enable smart controls in rooms, Point-of-Sale systems that manage reservations, Call Accounting Systems that track and record customer calls, keyless entry systems, and mobile apps that facilitate easy booking and service requests are popularly used in addition to operative technologies such as Property Management Systems, Hotel Accounting Systems, Local Area Networks (LAN).{1} These technologies collect vast volumes of data daily due to the nature of operations. Such data necessarily includes personal information such as names, addresses, phone numbers, email IDs etc. and sensitive information such as gender, bank account and payment details, health information pertaining to food allergens etc. Resultantly, the breach and loss of such critical data impacts customer trust and loyalty and in turn, their retention within the business. Lack of adequate cybersecurity measures also impacts the reputation and goodwill of an HI entity since customers are more likely to opt for establishments that prioritise the protection of their data. In 2022, cybercriminals syphoned 20GB of internal documents and customer data from Marriott Hotels, which included credit card information and staff information such as wage data, corporate card number and even a personnel assessment file. A much larger breach was seen in 2018, where 383 million booking records and 5.3 million unencrypted passport numbers were stolen from Marriott’s servers.{2}

Cybersecurity is also central to safeguarding trade secrets and key confidential trade information. An estimate of US $6 trillion per year on average amounts to losses generated from cybercrimes.{3} The figure, however, does not include the cost of breach, expenses related to incident response, legal fees, regulatory fines etc which may be significantly higher for a HI entity when loss of potential profits is factored in.

Cybersecurity is also central from a legal standpoint. Legal provisions in various jurisdictions mandate the protection of guest data. In India, the Digital Personal Data Protection Act 2023, imposes a penalty of up to Rs. 50 Crores on a breach in observing obligations to take reasonable security safeguards to prevent personal data breach.{4} Similarly, the General Data Protection Regulation (GDPR) of the European Union also has guidelines for protecting personal data. Several other industry-specific rules, such as those pertaining to consumer protection,  may also be applicable.

Breaches and Mitigation

There are several kinds of cyber security threats faced by an HI entity. “Fake Booking” is a popular method of cyber attack, whereby attackers build and design a website that is modelled exactly after the hotel’s legitimate website. Many customers end up using such malicious phishing websites thereby exposing their personal and sensitive personal data to threats. Additionally, the provision of free wifi within hotel premises, usually accessible freely to the public, implies that a malicious actor may introduce viruses and updates bearing malware. Other common cyber threats include denial of service (DoS) attacks, supply chain attacks, ransomware threats, SQL injection attacks (a type of attack where malicious code is inserted into a database to manipulate data and gain access to information), buffer overflow or buffer overrun (when the amount of data exceeds its storage capacity, implying that the excess data overflows into other memory locations and corrupt or overwrites data in those locations). 

One of the best ways to manage data breaches is to leverage newer technologies that operate on a “privacy by design” model. An HI entity must deploy web application firewalls (WAF) that differ from regular firewalls since they can filter the content of specific web applications and prevent cyber attacks. Another method to safeguard data is by deploying a digital certificate which binds a message/instruction to the owner/generator of the message. This is useful in preventing any false claims fraud by customers. Digital certificates may be deployed on distributed ledger technologies such as blockchain, that are noted for their immutability, transparency and security. Self-sovereign identities or Identifiers (SSI) are also a security use-concept of blockchain whereby individuals own and control their personal data, thereby eliminating reliance on central authorities.{5} In the hospitality industry, SSIs enhance cybersecurity by securely storing identity-related information on a decentralised network, thereby reducing the risk of data breaches. Users can selectively share their information, ensuring privacy and minimising data exposure. This approach not only protects guests' personal details but also streamlines authentication processes, making interactions safer and more efficient.

From a less technical standpoint, cybersecurity insurance may be opted for by a hotel to secure themselves and customer information against breach. Through such insurance, a hotel may cover the liability that arises from breaches caused by both first- and third-party actions.{6} Additionally, Payment Cards Industry Data Security Standards should be adhered to, since these standards ensure that businesses should apply best practices when processing credit card data through optimised security. Employee training and upskilling in basic, practical cybersecurity measures and good practices is also a critical component of a comprehensive cybersecurity strategy.
